Oktest 0.7.0 released - a new-style testing library

[Makoto Kuwata]

I released Oktest 0.7.0.
http://pypi.python.org/pypi/Oktest/
http://packages.python.org/Oktest/

Oktest is a new-style testing library for Python.
::

from oktest import ok
ok (x) > 0 # same as assert_(x > 0)
ok (s) == 'foo' # same as assertEqual(s, 'foo')
ok (s) != 'foo' # same as assertNotEqual(s, 'foo')
ok (f).raises(ValueError) # same as assertRaises(ValueError, f)
ok (u'foo').is_a(unicode) # same as assert_(isinstance(u'foo', unicode))
not_ok (u'foo').is_a(int) # same as assert_(not isinstance(u'foo', int))
ok ('A.txt').is_file() # same as assert_(os.path.isfile('A.txt'))
not_ok ('A.txt').is_dir() # same as assert_(not os.path.isdir('A.txt'))

See http://packages.python.org/Oktest/ for details.

NOTICE!! Oktest is a young project and specification may change in the future.


Enhancements and Changes
------------------------

* enhanced to allow users to define custom assertion functions. ::

import oktest
from oktest import ok
#
@oktest.assertion
def startswith(self, arg):
boolean = self.target.startswith(arg)
if boolean == self.expected:
return True
self.failed("%r.startswith(%r) : failed." % (self.target, arg))
#
ok ("Sasaki").startswith("Sas")

* rename 'ok().hasattr()' to 'ok().has_attr()'.
(but old name is also available for backward compatibility.)

* change 'chdir()' to take a function as 2nd argument. ::

def f():
... do_something ...
chdir('build', f)

# The above is same as:
with chdir('build'):
... do_something ...

* add document of 'oktest.helper.dummy_io()'. ::

with dummy_io("SOS") as io:
assert sys.stdin.read() == "SOS"
print("Haruhi")
assert io.stdout == "Haruhi\n"
assert io.stderr == ""

* fix 'oktest.tracer.Call#__repr__()' to change output according to
whether '==' is called or not. This is aimed to make output of
'ok(tr[0]) == [...]' to be more readable.

* change 'Runner#run()' to skip AssertionError if it is raised by
'assert ....' and not 'ok() == ...'.

* fix example code for some helper functions.
